Specification of Letters Patent.

Application filed February 24, 1910. Serial No. 545,599.

T 0 all whom it may concern Be it known that I. Howann D. COLMAN, a citizen of the United States. residing at lockford. in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in TextileWIachines. of which the following is a specification.

I n spinning fibers into yarn, the yarn is wound upon bobbins or the like, each bobbin containing a single thread. To produce a warp it is usual to rewind the yarn from the bobbins onto spools or cheese-tubes, each spool or tube holding a single thread of a length equivalent to the quantity of yarn upon a plurality of bobbins. A sufficient number of spools or cheeses are then rewound upon a section beam. It has also been proposed to rewind yarn upon a section beam directly from the bobbins.

This invention relates to winders having means for automatically uniting the ends of the threads on bobbins to the ends of the threads on the spools, cheeses, section beam or other yarn mass produced by the winder.

In application Serial No. 628,474 is shown a winder having means for automatically uniting the end of the thread on a cheese. When the thread. being wound exhausts, the loose end connected to the cheese becomes wound on the periphery of the cheese and 1s subsequently found by a traveling mechanism and tied to the end of the thread on a reserve bobbin.

The present invention has special. although not exclusive reference to machines for winding yarn from bobbins to spools, that is to say, to containers having flanges or heads at opposite ends to retain the yarn mass on the container. In such machines the yarn is traversed or guided relatively slowly while the spool is being rotated, so that the yarn is wound approximately circularly upon the spool, as distinguished from the spiral winding usedin the production of cheeses. As it is very difficult mechanically to find the free end of the thread upon the periphery of a spool, it is an object of this invention to provide such an organization of parts that the rotation of the spool shall be arrested before the exhausted thread is completely wound upon the spool, the loose end being caught and held in position for operation thereon by a traveling yarn-uniting mechanism.

Other objects of the invention will be apparent from the following description (if the present embodiment.

The embodiment herein shown of my invention comprises a spooler. (2., a machine for winding yarn from bobbins onto spools, and a mechanism arranged to travel along the spooler and attach the ends of the yarn on bobbins to the ends of the yarn on the spools. The spooler consists of a framework providing two parallel sides, each side being equipped with means for rotatablv supporting bobbins and means for supporting and rotating spools. 1n the present embodiment, the length of the sides and the speed of winding are so proportioned to the quantit) of yarn usually wound upon bobbins and to the speed at which the wiiidentending mechanism travels that shortly before said mechanism reaches a given bobbin. said bobbin will have been emptied or exbausted 1t wilhtherefore, be understood that the winder-tending mechanism ties the end of the yarn on a fresh bobbin to everv spool as said mechanism advances:

As shown in Figs. 2 and 3. the framework of the spooler may comprise a number of transverse frames 1 rigidlv united by suitable longitudinal members as the rods .3 and the two angle-irons 3. The spools are. sup ported from the angle-irons 3. while the bobbins lie in bobbin holders that are clamped upon two longitudinally extending rods 4. The rods 4. in this instance. are supported by arms 5 fixed to and rising from bars (3 that are rigidly attached to ,laterall;"extending arms 7 0 n the frames 1.

The bobbin holders mav be of an suitable construction. but preferablv partake of the form illustrated in Figs. 9. 9 and 1.0. As therein shown. the bobbin-holders are arranged in pairs. each pair accommodating a bobbin that is being unwound or has been exhausted and a reserve bobbin. In l-Fig. 8 a indicates an active bobbin and b a reserve bobbin. The bobbin-holder structure comprises a base 8 having thereon two pockets formed of loops 9 of cloth or other suitable material suspended from posts 10. The posts 10 are formed from an integral rod. the ends being attached to the base'S and the middle portion 1t? being bent into loop form. as indicated in Fig. 9. A guide. post 11 is fixed to the base in parallel relation to the posts 10 and arranged so as to form be tween itself and an adjacent post 10 a narrow opening for the passage of the yarn to the spool. The forward end of said post 11, is bent as at 12 and attached to one of the posts 10.

The build motion comprises. in this in stance, twoangle-iron rails 13 (Figs. 2 and 3) fixed to slides 14 which are slidablv mounted upon vertical guides 15 (Fig. 7) attached to the frames 1. To a rock shaft 16 are fixed a suitable number of levers 17 which are eonneeted by means of links 18 t0 the slides 14. The shaft 16 is rocked to raise and lower the build-rails 13 alternately by means of a cam 19 (Fig. 4) engaging a roller 20 on an arm 21 fixed on said shaft. and a weight 22 carried bv an arm 22 on the shaft 16. the weight holding the roller 20 against the cam 19. The cam 19 is mounted on a shaft 23 Which carries at one end a spur gear wheel 24 meshing with an intermediate gear 25, the latter meshing with a pinion 26 fast on a shaft 27 (Figs. 2 and 3). ()n the shaft 27 is a worm wheel 28 meshing with a worm 29 on a vertical shaft 30. Power to in U n site filth of tho melt.
